Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional joint connectors have a large number of parts, leading to increased size, cost, and weight due to their complex assembly process, which complicates manufacturing and maintenance.
Innovation Solution
A joint connector design that reduces the number of parts by integrating a housing with mounting passages for wire insertion, a terminal with connection parts, and a holder with fastening protrusions and circuit patterns, eliminating the need for a separate male connector and joint bus bar, and utilizing an elastic pressing part for secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a basic structure with female housing, male housing, holder, and joint bus bar is used, then the connector provides reliable electrical connection, but the number of parts increases leading to increased size, cost, and weight
Solution Approach 1:
The patent merges the male housing, female housing, holder, and joint bus bar into a single integrated connector structure. The housing includes integrated mounting passages for terminals and a fastening hole for the holder, eliminating the need for separate male and female housings and reducing the overall number of components while maintaining reliable electrical connections.
Solution Approach 2:
The holder serves multiple functions: it fastens the terminal to the housing, provides electrical connection through circuit patterns on its fastening protrusions, and replaces the traditional joint bus bar. This multi-functional design reduces the number of parts while ensuring reliable electrical connectivity.
2Ease of manufacture
If multiple separate parts are assembled, then the connector provides functional completeness, but the assembly process increases in complexity and time
Solution Approach 1:
By combining multiple components into a single integrated housing structure with pre-positioned mounting passages and fastening features, the assembly process is simplified. The terminal can be directly inserted and fastened without requiring separate assembly steps for multiple housings and holders, thereby increasing productivity.
3Reliability
If traditional joint connector structure is used, then electrical connection is established, but size, cost, and weight of the connector increase
Solution Approach 1:
The integration of multiple components into a single housing structure reduces the total material required and eliminates the weight of separate male housing, female housing, and joint bus bar components. The holder with circuit patterns provides electrical connection functionality without requiring additional heavy components.
Solution Approach 2:
The patent extracts and eliminates unnecessary components (male housing, female housing separation, traditional joint bus bar) from the traditional connector structure, retaining only the essential elements needed for electrical connection while reducing overall weight.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design reduces the size, cost, and weight of the connector while simplifying assembly and maintenance, allowing for easier pattern changes without mold modifications, and enhancing the fixing force through the use of copper, nickel, and gold plating on the fastening protrusions.
Implementation Method 1
A pressing part formed of an elastic body may be formed inside the fastening hole to fix and compress the fastening protrusions when the fastening protrusions are inserted into the fastening hole.
Implementation Method 2
Circuit patterns may be formed on the fastening protrusions of the holder so that the fastening protrusions are connected to the wires when the fastening protrusions are inserted into the insertion holes of the terminal.
